June 28 - Tau Day

                                                                                        Posted on June 28, 2018


Given the popularity of Pi Day on March 14 (the mathematical constant pi being 3.14), it would seem obvious that Tau Day (June 28, because the mathematical constant tau is 6.28) would also catch on.



After all, pi is the irrational number formed when the circumference of a circle is divided by diameter of that circle...





And tau is the irrational number formed when the circumference of a circle is divided by radius of that circle. 


The two mathematical constants are really similar - but we use the radius, not the diameter, in most circle descriptions and definitions. So many argue that tau is better than pi, and we should certainly celebrate it as often or more.


But...but Pi Day has all those circular pies, and everyone likes pie...and...and is there anything even remotely delicious called tau?





Hmm...


Since tau is equal to two time pi, I guess we have to have TWO pies on Tau Day! And that makes Tau Day twice as nice, am I right?

Here are a few more Tau Day memes:





You may be wondering what gives with the black-and-white circle design. This ying-yang symbol is the symbol of Taoism, which is a Chinese religion or philosophy that emphasizes living in harmony, cycles of nature, and balance between opposites. The fact that the black part of the design is a mirror image of the white part helps us to picture the importance of darkness AND light, day as well as night, ugliness alongside beauty.


The fact that the symbol of Tao is based on circles is one thing that makes Tau Day pretty rad! So, ying-yang-symbol pies?

Or some other ying-yang-based treat?

June 27 - Happy Birthday, Emma Goldman

Posted on June 27, 2018


Today's famous birthday was a woman whose life as a whole was a complex mix of good and bad actions and ideas. One of the most marvelous things about this woman is that she was not afraid to be her own self, not afraid to have unpopular - even radical - ideas. Another great thing about her was that she was willing to change her mind when she was presented with reason to do so.


Emma Goldman was born to a Jewish family in what was then Russia, but is now Lithuania, on this date in 1869. She emigrated with her sister to the United States at age 16, and she became a writer, lecturer, and activist, interested in political philosophy and anarchy, women's rights and other human rights, freedom of speech, atheism, birth control, even prison conditions. She started a journal called Mother Earth.

Since Goldman was imprisoned several times, she got a first-hand glimpse of the latter.

What I don't like was Goldman's occasional violent and even murderous actions and attempted actions. I do think there is a time for self-defense, of course, but taking really bad actions for what you consider good, moral reasons is how EVERY murderer justifies his or her violence. It's a pretty slippery slope.

This kind of "killing" is good:
killing ignorance itself (rather than ignorant people),
killing bigotry itself (rather than bigoted people),
killing superstition itself (rather than superstitious people).

Around 1920 Goldman was deported to Russia. At that point, Russia had just gone through enormous shake-ups, with the Czar being put to death and Bolsheviks and Vladimir Lenin taking over the government in the name of communism. Goldman found much more to admire in the philosophy of communism than in capitalism, so she was at first enthusiastic about Russia's October Revolution, but she soon saw that the new leaders - especially Lenin - were narrow minded and repressed ideas that differed from their own.

And when I say "repressed ideas," I mean that Lenin ruthlessly imprisoned or killed those who dared to disagree with him. He closed down newspapers that dared to disagree and had those in other political parties beaten or killed.

I am glad to say that Emma Goldman saw all that and denounced Lenin and the Bolsheviks. She wrote a book about it and no doubt gave lectures on what she had seen first-hand.


Goldman ended up living in many different nations and died in Canada at age 70.

When you see memes or quotes being passed around on social media, you should probably check them out to make sure they are legit. Here's a quote that there is no evidence Goldman ever said or wrote:

This is one of the most commonly shared Goldman
quotes, which is really frustrating, since it's
probably just a fake quote.

Also, by the way, even though Goldman was
an anarchist, I am not. Also, I would say that
voting CAN change things and has
many times. However, voting doesn't always
change things, and elections are sometimes unfair.

I would say that voting in a democracy is
necessary to making good changes - but not
sufficient. In other words, we should all vote,
but we should also do more civic action,
like contacting our elected officials, protesting
bad laws, and applying to courts for justice.

Here is another quote that is often attributed to Goldman:


There are many other very similar versions
of this quote. That's probably a tip that
Goldman never wrote it...

This quote shares an idea that Goldman did hold, but she didn't ever say or write that idea so briefly. Instead, she wrote about an incident in which a young man who was involved in one of her movements came up to her as she was dancing and whispered that she was harming the cause - by dancing!

She writes that she was furious with him and wanted no part of a movement that demanded she give up every joy "for the cause." She wrote, further:

 

June 26 - Happy Birthday, Babe Didrikson Zaharias

Posted on June 26, 2018

One of the greatest female athletes of all time...

But during her lifetime, some people criticized Babe Didrikson (later Babe Zaharias) as being too "manly."

And one sportswriter wrote about her, "It would be much better if she and her ilk stayed at home, got themselves prettied up, and waited for the phone to ring."

Yi-ikes!

The fact that a sportswriter was willing to put something like that into writing, let alone to be published under his own name, shows you just how sexist the world was during Didrikson's lifetime!


So...you are probably wondering what sport Didrikson played.

To which I would counter, "Don't you mean what sportS, plural, she played?"

Didrikson was an expert diver, roller skater, and bowler, she participated in other sports as well, she accomplished a TON in basketball, baseball / softball, and track and field, and she is best known for her dominance of women's golf!







Wow!

Her accomplishments include winning gold medals in the Olympics and winning 10 LPGA golf tournaments.

Didrikson changed the way that people thought about female athletes, because she was strong and she was so direct in the way that she accepted her own strength. Unfortunately, she was struck by colon cancer, but fortunately, she used her fame to raise money to fight cancer, to raise awareness of cancer, and to make people more willing to openly acknowledge and talk about cancer. 





She died of cancer at age 45, which is way, way too young - and she was still one of the top-ranked golfers the day she died!
